Leucostele bolligeriana is a species of cactus found in Chile.[1]

Description

Leucostele bolligeriana is characterized by its trunkless structure and upright or hanging growth, reaching heights between 2 and 6 meters. The branches, with a diameter of 18 cm, have 17-20 ribs, each measuring 0.6–2 cm in width and 3 mm in height. The stem is covered with ovate areoles in yellow, gray, and black, measuring 2 mm in height and 6–8 mm in width. These areoles host spines in shades of light green, grey, and brown, comprising 1–6 central spines (0.3 to 6 cm long) and 15-16 radial spines (0.5 to 2 cm in length).

Leucostele bolligeriana produces 1 to 3 flowers that are greenish yellow or yellowish white, featuring longitudinal lines and growing subapically. These flowers, measuring 14 cm in length, have a prominent ovary and floral tube covered with abundant brown hairs. The fruit is 2–3 cm long and 3–4 cm in diameter, covered with triangular scales and brown and grey hairs. The pulp of the fruit is white, and the seeds measure 1.8 mm in length and 1.0 mm in width.[2]

Distribution

This plant is native to the hills of the Coastal Cordillera in Cardenal Caro, growing in proximity to the sea and on steep slopes.[2]

Taxonomy

Initially collected in Punta de Lobos in 2003 by Helmut Walter and classified as Echinopsis bolligeriana, the species was named in honor of Dr. Thomas Bolliger, a cactus curator in Zurich. In 2012, Albesiano identified Trichocereus chiloensis var. conjungens as a synonym, based on similarities in rib and spine morphology.[2] In 2012, Boris O. Schlumpberger reclassified the species into the genus Leucostele.[3]
